Abstract

The invention provides a rubber sealing material. The rubber sealing material consists of the following components in parts by mass: 80-90 parts of hydrogenated butadiene-acrylonitrile rubber, 25-35 parts of acrylate rubber, 3-5 parts of oleyl alcohol, 10-12 parts of diacetyl peroxide, 3-5 parts of aluminum oxide, 5-8 parts of zinc oxide, 6-8 parts of high wear resistant carbon black, 0.3-2 parts of an anti-aging agent, and 3-5 parts of sulfur. The rubber sealing material provided by the invention can bear the pressure of 410 Mpa, and has the advantages of low friction coefficient (0.20-0.22) and strong wear resistance.

Description

technical field [0001] The invention belongs to the technical field of materials, and in particular relates to a rubber sealing material. Background technique [0002] Sealing products are important basic components of all kinds of machinery, and almost all industrial sectors cannot do without it. The quality of the sealing element is directly related to the service life and operational reliability of the machine. If the quality of the seals is poor, it will cause loss and trouble if it is light, and it will cause serious accidents if it is serious. In an environment with high working pressure, the sealing ring bears a large load, which requires the sealing product not only to have good sealing performance, but also to have good high-pressure resistance. Contents of the invention [0003] The invention provides a high-pressure-resistant rubber sealing material capable of withstanding a pressure of 410MPa. [0004] The invention provides a rubber sealing material, which...
